DJ Whoo Kid: Look Out Jay Z ... Odell Beckham Jr. Knows the Magic Words

Take Odell Beckham Jr.'s amazing football talent and add his apparent rapping skills -- and he could be ready to take the throne from the current king of NYC ... according to one expert.

We asked Shade 45 and the G-Unit's DJ Whoo Kid to review the video TMZ Sports first posted -- OBJ spitting bars during a party -- and he was into the freestyle. Whoo was most impressed by Beckham's choice of lyrics.

In fact, he thinks there's a very good reason for Jay Z to give Beckham a shot ... as a rapper.
